[GNC] Bad date not caught

[john]

That would be because the FAA has been trying and failing to upgrade their IT for darn near 50 years. MMDDYY was the standard way to code dates in the 1960s. Getting that fixed was what the Y2K apocalypse was about.

But while it's a nice standard that works a tread for the backends it's not something to impose on users. If you want to write dates as MM-DD-YY GnuCash should accept that.

Of course, just because this is an international standard, doesn't mean that everyone (including governments) follows it.  This includes the US FAA. which presumes MM-DD-YY.
